基于落锤式弯沉仪的公路路基特性研究综述

摘要

The paper introduces the application background of FWD at home and abroad,analyzes FWD testing principles,and summarizes meth-ods of analyzing subgrade performance with FWD from aspects of nonlinearity,moisture and density,which will be good for rationally evaluating subgrade characteristics and influence of relevant parameters upon road structure.%介绍了落锤式弯沉仪在国内外的应用背景，在分析落锤式弯沉仪测试原理的基础上，从非线性、含水率及密实度方面，总结了利用落锤式弯沉仪分析路基性能的方法，有助于合理评价路基特性及相关参数对道路结构的影响。
